Description
N80(1)/PSL.1, N80(1)/PSL.2, N80(Q)/PSL.1, N80(Q)/PSL.2, N80(Q)/PSL.3
Characteristics:
1. Materials: The chemical compositions have been carefully determined to provide resistance to sulfide stress corrosion as well as to insure complete through wall hardening.
2.Heat Treatment: Quenching and Tempering are conducted under rigid temperature control to assure homogeneous physical properties and microstructures.
3.Micro Structure: These grades exhibit fully tempered martensite which is considered to be the most desirable for resistance to sulfide stress corrosion cracking.
4. Tensile Properties and Hardness: Yield Strength is limited within a narrow range and hardness is controlled to within the predetermined maximum limit.
5. Sulfide Stress Cracking (SSC) Performance: Whole grades are designed for 85% or 90% SMYS in NACE condition. Excellent SSC resistance has been achieved through rigorous, chemical composition, heat treatment, microstructure, tensile properties, hardness and so on.
Pipe inspection:
A full length non destructive inspection is performed in accordance with API 5CT for external and internal, longitudinal and transverse defects with a standard notch depth equal to 5% of the specified wall thickness.
